Mod BIOS For Asus EAH4850

Thanks to all who helped here, especially Gareth :) All back up and running!

Mixed results, started off at 730/1130 - Tearing, temps @63° which is good. :)

720/1100 - Excellent, temps @ 62° but only yields in between an extra 2 and 4 fps compared with original bios @ 700/1080.

As ghost mentioned, some cards can`t get up to 750/1150 it seems.

In perspective though, out the box 3dmark 06 scored 12132, with 700/1080 12636 and with modded bios@720/1100 12871.

8.9 drivers? they should work. point it to C:\ATI\SUPPORT\8-9_vista64_dd_ccc_wdm_enu_68906\Packages\Drivers\Display\LH6A_INF\

if u wanna flash to your old bios just use your backup bios or go to http://www.mvktech.net/component/option,com_remository/Itemid,26/ or techpowerup and download asus bios.

Solved the problem about the graphics card not being recognised by Vista 64 bit, after using winflash to update BIOS, simply used atiflash to reflash 4850 with stock bios (from mvktech) in DOS (ran it from floppy), was then able to update drivers from 8.7 to 8.9, graphics card being fully recognised by Vista 64 bit...

I think the moral of the story is, if using winflash to uninstall drivers before running it, or simply use atiflash to flash in DOS!

EDIT:

Dave, just saw you have the same issue I had, try using atiflash to flash in DOS...:)

i've used winflash so many times with out problem.. u just need to close background tasks and make sure your system is stable. best to do it with everything at stock.
 
Thanks again Gareth :) I now have a bootable 4Gb pen drive which I will keep for nothing else. I`ll just keep adding any applicable apps (ASUS Ezflash for mobo for example) and updated bios ;)

How did you make pen drive bootable?

I tried to make a flash drive bootable for the purpose of flashing in DOS, but it failed miserable, I used the guide from Here..."Making a bootable USB stick"...

There's a really useful HP tool you can use, whats your email address, I'll send it you.

It was the HP tool that I was using, "SP27213", however, using the link supplied by Gareth, it would seem there is a more recent version, "SP27608", so the problem may have been that I was using an old version of the HP utility, or simply that it is one that cannot be made bootable, but I have a few others (flash drives) I can try, if the need arises again....

Thanks for the link Gareth...:)

Have you got the DOS files too? You need them to get it to work.

Well, I thought I had, I ran the HP utility, then copied a number of files from a download called "USBImage" onto it, also with the bios....

However, if you look in my Trust you will find my OcUK email address, I think it would be worth having the DOS files you have, as I may just not have been using the most recent ones.

Thanks. :)
 
Copying the files you need wouldn`t work. They have to be created. The USB-Boot zip file contains loads but you only see a couple of files on the boot pen after formatting :)
